VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 459,694, datedSeptember 15, 1891.

Application filed July 18,1890. Serial No. 359,211. (No model.)

To @ZZ wtom, t may concern.-

Be it known that I, WARREN 111. ABBOTT, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Vapor-Burners, of which the followingl is aspecification.

This invention has special relation to vaporburners of the kindshown'and described in United States Letters Patent No. 373,874, grantedto me November 29, 1887, though parts and features of the improvementsare applicable to vapor-burners of other forms.

It is the Object of my invention to provide improvements whereby accessmay be more readily had than heretofore to the Waterchamber in theretort or mixing-chamber in order to repair or rearrange thewater-chamber or its equipments.

It is also the object of my invention to provide improvements wherebythe water in the water-chamber may be more thoroughly vaporized ornebulized before issuing from the water-chamber than heretofore.

It is also the object of myinvention to provide such improvements aswill secure a uniform supplyof vapor to the burners, whether the deviceshould be in level position or moved out of level.7

Itis also the object of my invention to provide other improvements invapor-burners incidental to the foregoing, as will the more readilyappear from the description hereinafter given.

Reference is to be had tothe annexed d rawings,`and to the letters ofreference marked thereon, forming a part of this specification, the sameletters designating the same parts orfeatures, as the case may be,wherever they occur.

Of the accompanying drawings, Figure 1 is a vertical central sectionalview, parts being represented in elevation, of my improved vapor-burner,the section being taken on the line 1 1 of Fig. 2. Fig. 2 is ahorizontal seetion of the same, taken on the line 2 2 of Fig. 1. Fig. 3shows in sectional View a modilied manner of connecting the water-chamber with the retort or mixing-chamber. Fig. 4 is acrosssection showing amodiiied form of drip-pan,x

jacket, and deliector. Fig. 5 is a top plan view of my improvedwater-chamber.

In the drawings, referring to Figs. 1, 2, and 5, a designates thedrip-pan; b, the jacket seated thereon; c, the retort or mixing-chambed, the deflector or spreader arranged upon the retort; e, thewater-supply pipe; f, the water-chamber in the retort, with which thepipe e communicates; g, the oil-supply pipe communicating with theretort; h h, the burners, ande' the pipe communicating between theretort and burners for the purpose of supplying the latter with vapor.

The drip-pan a is provided at points, preferably at the corners, with aflange j, which extends upwardly outside of the lower edge of the jacketb, so as to maintain the lat-terin place on the pan, which isserratedornotched at its edge, as at 7c, said notches vaffording meansfor supplying air to the burners.

The water-chamberf, instead of being constructed-integrally with thepipe e and provided with a cap, is made as a separate part,screw-threaded exterior-ly at its base, as at Z, and provided withperfor-ations in its upper end, as at m. This construction enables thewater-chamber to be tapped into the base of the retort, as shown in Fig.1, and the water-pipe e to be tapped into the lower end of thewater-chamber, so that in order to gain access to the water-chamber itis not necessary to disconnect the same from the retort, (a thing verydifficult of accomplishment, since the chamber quickly becomes burned onthe retort,) but the end mentioned may be accomplished by simplyunserewing the pipe e fromthe chamberf.

The chamber f may be provided with asbestus n or other suitable materialand covered witha piece of wire-gauze or other foraminous material a',which provision serves to assist in breaking the vapor 'escaping from ving and arranging it as shown and described I am enabled to uniformlysupply the burners with vapor and render it unobjectionable to have theburner placed in other than a level position.

The burners 7L are connected with the crosspipe o, so that they may bemoved axially, this construct-ion and arrangement being provided inorder to vary the direction of the flame, which is governed by thecourse of the vapor issuing from the apertures p in the burners, and soproject the llame with greater or less directness against the retort c.In the present instance the burner-pipes have a screw-threadedconnection with cross-pipe o similar to that by which pipe 1I isconnected with the cross-pipe o.

Instead of connecting the water-chamberf with the bottom of the retort,so as to stand vertically therein, as shown in Fig. l, it may beconnected with the end of the retort and be made to take a horizontalposition, as shown in Fig. 3, in which case the oil-supply pipe g andvapor-supply pipe 2' may be connected with the bottom of the retort orbeotherwise suitably connected and arranged.

In instances where it desirable to admit air to the burners from thecenter of the device the drip-pan a is provided with depressions q alonglines adjacent and in proximity to the burner-pipes h, and the innerwalls of such depressed portions are provided with air-inlets 1321s isshown in Fig. 4. By thus arranging the air-inlets the dames are moreequally and uniformly supplied with air, and they are forced against ortoward the walls of the inclosing covering. In this case the air may ormay not be admitted at the outer edges.

Instead of providing a jacket and detlector constructed as separateparts formed and arranged as shown in Figs. l and 2, I may construct thejacket as a cover for the burners, retort, and their adjunets, havingits upper portion provided with numerous apertures S,

the cover being' so arranged that its lower edge will rest upon thedrip-pan, as is also shown in Fig. 4, the objectof said cover being toinc-lose the retort and form a seat or bearing for anything that is tobe heated.

It is obvious that various changes may be made in the form andarrangement of parts shown in the drawings wit-hout departing from thenature and spirit of my invention.

Having thus explained the nature of my improvements and described waysof constructing and using the same, I declare that what I claim is- 1.In a vapor-burner, the combination, with the retort having oil supplyand discharge pipes and burners, of the water-chamber opening into saidretort and provided with exit-apertures, asbestus-or similar material inthe water-chamber, and a sheet or coveringu of foraminous materialbetween the asbestus and said exit-apertures, as set forth.

2. 'lne herein-described improved vaporburn er, comprising the retortand its adj uncts, the parallel burners h, connected to said retort, andthe drip-pan provided with a series of obliquely-arranged air-inletholes or ports between the burners, as set forth.

The herein-described improved Vaporburner, comprising the retort and itsadj uncts, the burners connected therewith, the drippan, and theremovable cover entirely inclosing said retort and burners and adaptedto rest at its lower edge upon and supported by the drip-pan andprovided in its upper part with apertures, as and for the purposesetforth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 15th day of July, A. D.1890.

VARREN M. ABBOTT.
